AI Technical Summary

Benefits of technology

The invention solves the problem of traditional electromechanical locks being easily unlocked with just a few pulses of force. The anti-shock feature prevents this, making the lock more secure.

Problems solved by technology

Unfortunately, because of their peculiarity, electromechanical locks prove to be easily subject to opening with dexterity by shock.
These types of openings allow to close again the electromechanical locks afterward without causing any damage to their functioning nor leaving signs of the occurred opening thus making it impossible to ascertain that there was an opening with dexterity by a third party.

Abstract

The present invention concerns an electromechanical lock (1), comprising:a solenoid (2)a movable locking element (3) displaceable by said solenoid (2) into an unlocking position of the lock (1)a spring (4) acting on said movable element (3) to hold it in a locking position of the lock (1) with the solenoid (2) in a de-energized condition wherein said movable element (3) comprises an anti-shock shaped portion (31,31′,31″,31′″) and said lock (1) comprises an engagement means (8,8′,8″,8′″) for said anti-shock shaped portion, said engagement means (8,8′,8″,8′″) is displaceable into an engagement position in which it interferes with the anti-shock shaped portion (31,31′,31″,31′″) in order to prevent said movable element (3) from displacing into the unlocking position of the lock wherein said lock it further comprisesa substantially cylindrical and hollow rotor (6), intended to house said solenoid (2) and said movable element (3) such that one end of the latter provided with said anti-shock shaped portion (31) externally protrudes from said solenoid (2)a fixed block or stator (9)a stop bar (81) radially displaceable from and towards an interference position between rotor (6) and stator (9) to allow or prevent rotation of the former with respect to the latter.

Description

TECHNICAL FIELD[0001]The present invention relates to the field of electromechanical locks; this term is intended to indicate those locks equipped with a movable locking element displaced by a solenoid, in turn activated by an unlocking electrical signal.STATE OF THE ART[0002]In the electromechanical locks the movable element cooperates with the operating elements of the lock that control the bolt and that vary depending on the types of locks.[0003]In general, in these locks the movable element is stably held in the locking condition of the lock thanks to a spring.[0004]When the unlocking electrical signal (which can be generated by a key provided with an electrical battery or by an electrical circuit connected to a control button) is imparted to the solenoid, this latter acts on the movable element bringing it into the unlocking condition of the lock.[0005]This condition is maintained until the electrical signal that energizes the solenoid continues; when the electrical signal ceas...
